Filed: 2000-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce as much as possible a position shift between an ink pressurizing chamber having a heating resistor and an ink ejection nozzle corresponding to the ink pressurizing chamber. SOLUTION: In this method, a correction member 4 having a coefficient of linear expansion roughly equal to a coefficient of linear expansion of a substrate member 6 is stuck to a nozzle forming member 2 and then the expansion or contraction of the nozzle forming member 2 due to temperature variation is executed along the coefficient of linear expansion of the substrate member 6. A forming interval L1 of the ink ejection nozzles at a temperature that a print head 1 is used is determined by the following expressions.  L1=L2(α2ΔT-1)/(α1ΔT-1) L2: a nozzle interval at the use temperature after the print head is completed α1: a coefficient of linear expansion of the nozzle forming member α2: a coefficient of linear expansion of the correction member T1: a sticking temperature when the nozzle forming member and the correction member are stuck with each other ΔT: a difference between the sticking temperature T1 and the use temperature.
